Do not expose power tools to rain or wet  
conditions. Water entering power tool will  
increase the risk of electric shock.  
Do not abuse the cord. Never use the cord for  
carrying, pulling or unplugging the power tool.  
Keep cord away from heat, oil, sharp edges or  
moving parts. Damaged or entangled cords  
increase the risk of electric shock.

When operating a power tool outdoors, use an  
extension cord suitable for outdoor use. Use of  
a cord suitable for outdoor use reduces the risk of  
electric shock.  
If operating a power tool in a damp location is  
unavoidable, use a residual current device  
(RCD) protected supply. Use of an RCD reduces  
the risk of electric shock.

General Power Tool Safety  
Warnings  
WARNING Read all safety warnings and all  
instructions. Failure to follow the warnings and  
instructions may result in electric shock, fire and/or  
serious injury.  
medication.  
A
moment of inattention while  
operating power tools may result in serious  
personal injury.  
12. Use personal protective equipment. Always  
wear eye protection. Protective equipment such  
as dust mask, non-skid safety shoes, hard hat, or  
hearing protection used for appropriate conditions  
will reduce personal injuries.  
13. Prevent unintentional starting. Ensure the  
switch is in the off-position before connecting  
to power source and/or battery pack, picking  
up or carrying the tool. Carrying power tools with  
your finger on the switch or energising power tools  
that have the switch on invites accidents.  
14. Remove any adjusting key or wrench before  
turning the power tool on. A wrench or a key left  
attached to a rotating part of the power tool may  
result in personal injury.  
15. Do not overreach. Keep proper footing and  
balance at all times. This enables better control  
of the power tool in unexpected situations.  
16. Dress properly. Do not wear loose clothing or  
jewellery. Keep your hair, clothing, and gloves  
away from moving parts. Loose clothes,  
jewellery or long hair can be caught in moving  
parts.  
Save all warnings and  
instructions for future reference.  
The term "power tool" in the warnings refers to your  
mains-operated (corded) power tool or battery-operated  
(cordless) power tool.  
Work area safety  
1.  
2.  
Keep work area clean and well lit. Cluttered or  
dark areas invite accidents.  
Do not operate power tools in explosive  
atmospheres, such as in the presence of  
flammable liquids, gases or dust. Power tools  
create sparks which may ignite the dust or fumes.  
Keep children and bystanders away while  
operating a power tool. Distractions can cause  
you to lose control.  
3.  
Electrical safety  
4.  
Power tool plugs must match the outlet. Never  
modify the plug in any way. Do not use any  
adapter plugs with earthed (grounded) power  
tools. Unmodified plugs and matching outlets will  
reduce risk of electric shock.  
5.  
Avoid body contact with earthed or grounded  
surfaces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of  
electric shock if your body is earthed or grounded.  
17. If devices are provided for the connection of  
dust extraction and collection facilities,  
ensure these are connected and properly used.  
Use of dust collection can reduce dust-related  
hazards.

Power tool use and care  
5.  
6.  
Ventilate your work area adequately when you  
perform sanding operations.  
Some material contains chemicals which may  
be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow material  
supplier safety data.  
Use of this tool to sand some products, paints  
and wood could expose user to dust  
containing hazardous substances. Use  
appropriate respiratory protection.  
Be sure that there are no cracks or breakage  
on the pad before use. Cracks or breakage  
may cause a personal injury.  
18. Do not force the power tool. Use the correct  
power tool for your application. The correct  
power tool will do the job better and safer at the  
rate for which it was designed.  
19. Do not use the power tool if the switch does  
not turn it on and off. Any power tool that cannot  
be controlled with the switch is dangerous and  
must be repaired.  
20. Disconnect the plug from the power source  
and/or the battery pack from the power tool  
before making any adjustments, changing  
accessories, or storing power tools. Such  
preventive safety measures reduce the risk of  
starting the power tool accidentally.

8.  
SAVE THESE INSTRUCTIONS.  
21. Store idle power tools out of the reach of  
children and do not allow persons unfamiliar  
with the power tool or these instructions to  
operate the power tool. Power tools are  
dangerous in the hands of untrained users.  
22. Maintain power tools. Check for misalignment  
or binding of moving parts, breakage of parts  
and any other condition that may affect the  
power tool’s operation. If damaged, have the  
power tool repaired before use. Many accidents  
are caused by poorly maintained power tools.  
23. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges  
are less likely to bind and are easier to control.  
24. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions,  
taking into account the working conditions  
and the work to be performed. Use of the power  
tool for operations different from those intended  
could result in a hazardous situation.  
WARNING:  
DO NOT let comfort or familiarity with product  
(gained from repeated use) replace strict adherence  
to safety rules for the subject product. MISUSE or  
failure to follow the safety rules stated in this  
instruction manual may cause serious personal  
injury.
